Police have issued a new warning after an elderly couple were conned in a scam involving iTunes and Steam vouchers bought at supermarkets.

In the latest case the couple were convinced by a cold-caller who claimed to be a tax inspector demanding vouchers be bought at a local Morrisons.

The incident in Hull follows an almost identical scam on a woman in Grimsby who was told to buy iTunes vouchers from a local Tesco in Yarborough.

A third incident happened in Lincolnshire at the beginning of March, when a victim gave away over £200 by purchasing iTunes vouchers and providing the codes to a suspect.

And now Humberside Police have warned people to beware of the fraud.

A spokesperson for Humberside Police said: "We have recently had yet another case of telephone calls being made by people impersonating HMRC Tax officers.

"They told an elderly couple that they owe tax and have to pay in the form of ‘iTunes’ (music) or ‘Steam’ Vouchers (gaming platform gift cards).

"They threatened the couple, saying that if they don’t pay they will be arrested and taken to court.

"Sadly the couple believed the scammer and bought vouchers amounting to a large sum of money."

The couple purchased the vouchers from Morrison’s supermarket on Holderness Road in Hull, who noticed there was something not quite right about a recent transaction and contacted the police to report it; which was what prompted the investigations.

PCSO Chelsea Williams dealt with the case and was so concerned that other people might become victims, she said: "It is very easy to believe these people when they call you, they seem so genuine.

"They come across as though they work for HMRC and they seem to have a lot of knowledge about the local area and which shops to go to for the vouchers."
